SUBSTRATE PREPARATION FOR APPLICATION OF CERESIT R 777

Subfloors must comply with the requirements of comparable national standards. In particular they must be clean, free from structural defects, firm, permanently dry and free of release agents. In case of cement based substrates, any laitance must be removed using suitable machines. Always grind sulphate screeds (with sandpaper, grain size 16) and vacuum clean.

MIXING OF CERESIT R 777

Shake well before use. On screeds dilute CERESIT R 777 1:1 with water, on concrete floors use CERESIT R 777 undiluted.

APPLICATION OF CERESIT R 777

Apply evenly with a lambskin roller. Do not allow the primer to form puddles. A second coat may be necessary on porous, very absorbent substrates after drying.
